IV (Intravenous)
An administration route abbreviation designating delivery of fluids or medications directly into a vein.
💬 In Plain English
IV stands for "intravenous," meaning directly into a vein. In veterinary hospitals, veterinary technicians place an intravenous catheter into a vein in your pet’s front leg (cephalic vein), back leg (saphenous vein), or neck (jugular vein). An IV catheter provides an immediate lifeline: medications enter the bloodstream with 100% absorption in seconds, and IV fluids can be continuously infused to support blood pressure, hydrate sick kidneys, and flush out toxins.
